Procedure

A 25 mL reaction vessel was charged with (3E)-3-(5,5-dimethyl-4-morpholin-4-ylfuran-2(5H)-ylidene)-6-iodo-1,3-dihydro-2H-indol-2-one (100 mg, 0.23 mmol), methyl thiosalicylate (77 mg, 0.46 mmol), PdCl2(dppf).CH2Cl2 (19 mg, 0.023 mmol), cesium carbonate (225 mg, 0.69 mmol) and 8 mL of anhydrous DMF. The mixture was purged with nitrogen and heated in 90° C. bath for 2.5 hours. The mixture was cooled to room temperature, diluted with 50 mL of water and extracted with EtOAc (3×50 mL). The organic layers were combined, washed with saturated NaHCO3 (50 mL), brine (2×50 mL), dried over Na2SO4, and concentrated to give a brown oil. Purification of the oily mixture by silica gel chromatography eluted with 1-10% MeOH/CHCl3 provided methyl 2-{[(3E)-3-(5,5-dimethyl-4-morpholin-4-ylfuran-2(5H)-ylidene)-2-oxo-2,3-dihydro-1H-indol-6-yl]thio}benzoate as a brown solid.
